As most fans know, the cabin used in Friday the 13th: The Final Chapter was used for some reshoots on The New Blood entry. Here is director, John Carl Buechler, and actress, Elizabeth Kaitan from the scene.

The side of the house is used for one establishing shot....

Screenshots...

Inside, Robin leaves "Tommy's room", goes to the bathroom door, and another bedroom door, before going into the third bedroom....

Screenshots....

Inside the room, she finds a cat and her boyfriends head, before she is rudely interrupted by Jason and thrown out the window...

Screenshots...

The window magically turns her into a stuntperson thankfully....

This room was Trish's room in The Final Chapter, but only appeared in a deleted scene....
